Hi Sam, I have checked file attached by you. I first made changes to its wavelengths and then observed them at the Receiver. It was working.After that I changed its sequence length to 4096 and tried to plot the graph. The graph I obtained was the one I attached earlier. It was from the file you have attached. After taking a screenshot I ddint save changes made to it.
However, the same problem occurs for both the files. Maybe I am not able select proper parameters or is there a mistake in selecting appropriate visualizer?
